Abstract :
A 91×91 switchless wavelength router using a concave Littrow mount-based holographic grating is designed. Coupling losses for all channels, spaced by 0.33 nm, are within -0.9 dB. In this device, the coherent crosstalk due to aberrations and diffraction at the aperture leads to a negligible penalty
